Actually not.
And of course if it where true, there would be no need to stick in that phrase multiple times.
But ok, i’ll bite. What was R’ Zweibel (and the Moetzes Gedolei Hatorah of America on whose behalf he was writing) looking to add wit h the phrase “and those mandated by a woman’s religious belief” If it didn’t add anything to “necessary to preserve the life of the mother”?
If it was once, fine I agree don’t be medayek in every word but it is every single time.
Why not just say “necessary to preserve the life of the mother” And thats it, if yo uthink that is Halacha’s approach
